Objective assessment of robotic proctectomy (RP) workflow reveals key surgical steps significantly correlate with console time (CT) and total operative time (TOT), aiding in procedure standardization.

Area of Science:

  • Robotic surgery
  • Surgical workflow analysis
  • Procedure optimization

Background:

  • Surgical workflow assessments provide valuable insights into procedural variability.
  • An objective methodology was employed to evaluate workflow during robotic proctectomy (RP).

Purpose of the Study:

  • To objectively quantify surgical workflow during robotic proctectomy.
  • To identify specific surgical steps that correlate with operative time.

Main Methods:

  • Annotated 31 robotic proctectomy procedures.
  • Utilized Spearman's correlation to assess relationships between step metrics and operative times.

Main Results:

  • Key steps like splenic flexure mobilization and mesorectal division showed strong correlations with console time (CT).
